I feel partly it is the release of a new car kit every 6-8 months from manufacturers does not help things. However when the cars cost $250 racers were searching for the next cool car. HPI Pro 4 comes out and everyone loves the graphite version of the TC3. Then Xray enters the market with a new car that is all graphite and aluminum. All of the sudden molded chassis and components are eliminated due to the market demand of graphite plate chassis. Well graphite and aluminum does cost more than a molded plastic part.
I also feel a big part is the batteries. We need to stop these batteries wars. GP4300, IB4200, IB4200SHV, IB4200WE. What the hell? These batteries are good enough to run a 7t mod motor for over 5 minutes however the ruling organizations through out the world do not put a stop to these new cells from the battery manufacturers being IB or GP. Where will batteries be in 1 year from now? Instead of these battery companies making new cells they need to work on making cell life LONGER.
Hopefully someone will step up and put an end to the battery of the month club. It will have to be a manufacturer like Orion, Trinity, SMC, etc
As for motors, hats off to everyone Orion, Checkpoint, and Trinity for making their motors run great for multiple runs. Now we have brushless which is a great thing to see for mod racing. In the 19T and stock racing we can never change that as people love to tune their motors.
Tires have been improved immensely with CS 27 and RP30 as handout tires. Clubs are using these tires for their weekly club racing. Just like we did with tires we need to do with batteries.
